[0015] Embodiment 4: On the basis of embodiment 3, a boss is provided on one side of the inner wall of the inner tube 2, and the boss is arranged along the axial direction of the inner tube 2, and the monitoring chip 3 is wrapped in the boss at the lower end of the inner tube 2. The present invention adopts a boss arranged along the axial direction of the inner tube on one side of the inner tube, and wraps the monitoring chip in the boss, which effectively avoids the risk of the chip falling off and falling into the trachea; the establishment of an artificial airway can cause different degrees of damage to the airway mucosa, such as ischemia, erosion, hemorrhage, necrosis, etc., which can be found by bronchoscopy, and the monitoring chip can provide early warning at a depth that cannot be observed by the naked eye of the patient.

[0016] Example 5. Based on Example 3, the monitoring module is connected to the PLC controller via a data cable. The monitoring module includes an image acquisition module. The image acquisition module sends the collected secretion photos to the PLC controller. The PLC controller judges the secretions in the image through an image processing algorithm. If the secretions are excessive or too viscous, the PLC controller issues an alarm and humidification therapy needs to be strengthened in time. The present invention adopts the secretion photos collected by the image acquisition module, and uses computer vision technology to analyze the secretion images. If the secretion is excessive or too viscous, it can remind and strengthen the humidification treatment in time; the humidification effect classification includes satisfactory humidification: thin sputum, smooth suction; excessive humidification: excessively thin sputum, frequent sputum suction; insufficient humidification: thick sputum, not easy to suction; because the lower respiratory tract is directly connected to the outside world after tracheotomy, the physiological barrier function of the upper respiratory tract to warm, humidify and filter the inhaled gas is lost, resulting in excessive water loss in the trachea, which is easy to cause complications such as airway obstruction, atelectasis and infection. Sufficient airway humidification can play the role of anti-inflammatory, debonding, diluting sputum and keeping the airway open.

[0017] Embodiment 6: Based on Embodiment 5, the monitoring module further includes a temperature and humidity sensor, which can send the collected temperature and humidity to the PLC controller, and the PLC controller judges the satisfaction of the airway humidity by comparing the values ​​of the judgment module. The present invention uses a temperature and humidity sensor to detect the airway temperature and airway humidity, and sends the collected data to the PLC controller, and judges the satisfaction of the airway humidity by comparing the values ​​of the judgment module.

[0018] Embodiment 7: Based on Embodiment 6, the judgment module compares the detected humidity value with the preset value, but if the detected humidity value is between 30% and 60%, it is satisfactory; otherwise, the PLC controller issues an alarm and the humidification scheme needs to be adjusted. The present invention adopts a judgment module to compare the detected humidity value with a preset value, but the detected humidity value is between 30%-60%, which is satisfactory; otherwise, the PLC controller issues an alarm and the humidification scheme needs to be adjusted, wherein the humidification is satisfactory: the secretion is thin and can pass through the suction tube smoothly, usually the sputum in the airway can be sucked cleanly with one suction, there is no scab in the endotracheal tube, the patient is quiet, the respiratory tract is unobstructed, and the sputum degree is ‖º; insufficient humidification: the secretion is viscous and difficult to suck out, and it takes multiple times to suck the sputum in the airway clean, the patient is often irritable, and may have sudden dyspnea, cyanosis or SpO2 decrease, and the sputum degree is ≥Ⅲº; excessive humidification: the secretion is too thin, the cough is frequent, and continuous suction is required. Auscultation of the lungs and trachea reveals many sputum sounds, and the patient is often irritable, cyanotic, and has a decreased SpO2.

[0019] Embodiment 8: Based on Embodiment 6, the image acquisition module sends the collected sputum photos to the PLC controller, and the PLC controller extracts and analyzes the sputum color, texture and shape features in the image through an image processing algorithm, thereby obtaining a quantitative measurement result of the sputum viscosity. The present invention uses computer vision technology to analyze the image of sputum, and divides the viscosity of sputum into IV degrees, I° (thin sputum): sputum is like rice soup or white foam, and no sputum is retained in the suction tube after suction; II° (mild sticky sputum): sputum is white mucus thread-like, and a little mucus-like sputum is attached to the suction tube after suction, which can be easily washed away by water; III° (moderate sticky sputum): sputum is white mucus-like, thicker than II°, and more mucus-like sputum is attached to the suction tube after suction, and it can be washed away by washing with water 1-2 times; IV° (severe sticky sputum): sputum is sticky in appearance, mostly yellow, and has an irregular shape. The suction tube often collapses due to sputum block block, or obvious sputum can be seen attached to the inner wall of the suction tube, and it can be washed away by repeated washing with water for many times; using computer vision technology, the quantitative measurement result of sputum viscosity can be obtained faster and more accurately, and the detection process has the characteristics of non-contact and rapidity.

[0020] Embodiment 9: Based on embodiment 7, the monitoring chip 3 is also provided with an alarm flashing light, and when the PLC controller issues an alarm, the alarm flashing light can light up at the same time.

[0021] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
